Here is a concordance to the King James Bible.

A concordance helps you find a scripture in the Bible if you remember some of the words.  

For example, if you remember "delight yourself in the lord," look under delight, and you'll see that Psalm 37:4 is one of the places that word is used.  It says, "Delight thyself also in the Lord, and he shall give thee the desires of thine heart." 

In the listings, three letter abbreviations are used for the book names, followed by chapter:verse.  The chapter number and verse number are separated by a colon.
